FWIW, I work with a guy that has a big ***** Nissan Armada and had his doors done at DUB up in LA. They open like normal, or pivot out then swing up and go really high. It looks cool sitting there, but is a PITA to get in and out of with the doors up. He got them as a free promo, but it was about a 2k job to have the guys that really know what they're doing do it. I have seen a few around where guys did the cheap kit themselves, and it looks and works like that.
Good luck though, and yes, if I won the lotto one of my VXs in the fleet would have them, and maybe 30" spinners, and TuPac airbrushed on the hood.....
